WICK-RAISER FOR LAMPS.

SPECIFICATION forming part of Letters Patent No. 406,016, dated .I une 25, 1889.

Application filed August 16, 1888. Serial No. 282,882. (No model.)

To @ZZ whom it may concern;

Be it known that I, GEORGE lV. VOOD- WARD, of Brooklyn, in the county of Kings and State of New York, have invented a eertain new and useful Improvement in IVick- Raising Mechanism for Lamps, of which the following is a specification.

I will describe wick-raising mechanism embodying my improvement in detail, and then point out the novel features in claims.

The accompanying drawing a vertical section of a lamp showing a wick-raising mechanism embodying my improvement.

A designates the fount of the lamp, which may be of the usual or any ordinary construction.

A' A2 designate the inner and outer wicktubes of the lamp. The tube A is arranged concentrically within the tube A2, and at such a space therefrom as to admit a eylindrie wick B. The inner tube A of the wick-tube constitutes a draft-ii ue for the lamp. In the example of my improvement shown the outer tube A2 does not extend to the bottom of the reservoir, but terminates some distance above the same, so as to leave a space, whereby the lower part of the wick will be exposed to the oil in the reservoir. There maybe combined with the wick-tube air-distributers or draftplates and defiectors, in the usual or any suitable nianner. I have shown the upper part of the inner tube of the wick-tube as receiving within it a perforated metal thimble, which extends above the same.

The wick-adjusting mechanism consists of awick holder or sleeve O, to which the wick is attached. As shown, the sleeve surrounds the wick. The wick may be secured to this sleeve by sewing or by means of prongs, with which the sleeve is provided. This ring, in effect, constitutes a wick-carrier. Motion is transmitted to it it'or the purpose ot adjusting the wick.

The means employed to adjust the sleeve C consist, as here shown, of a rod D, iitted to a guide in the lamp-reservoir, so as to be capable of being reciprocated or moved lengthwise in a vertical direction. Its upper end extends through the top of the reservoir and is provided with a screw-threaded portion vabove the reservoir.

E designates a tube extending vertically through the reservoir. Extending through the tube so as to slide freely therein is a rod F. It will be seen that the tube serves to steady the rod F. The rod F near its upper end is, as shown, bent, and is provided near its extremity with an aperture, which engages the screw-threaded end of the rod D. A nut l) may be adjusted upon. the screw-threaded portion of the rod D beyond the rod F, so as to prevent the accidental detachment of the latter from the rod l). The rod F below the reservoir is provided with a hand-piece f, by which it may be moved upwardly or downwardly. In the example of my improvement shown the rod D has combined with it a tongue d, which tongue engages a loop on the sleeve C. 'By rotating the sleeve C the tongue d may be engaged er disengaged with said loop. IVhen, therefore, the rod F is moved upwardly or downwardly, it will, by means of this engagement with the rod D, cause the raising or lowering of the wick, as desired.

I have shown below the reservoir, and surrounding th-e rod F, a cylindrical projection G, constituting a linger-piece, which projection is soldered or otherwise secured to the lamp-reservoir. This projection is of such shape that two of the fingers of a hand may be inserted between a flange g formed thereon and the lamp-reservoir to facilitate the delicate adjustment of the wick, as thereby sudden or too extended movements of the wick in either direction are avoided.

It will be seen that by my improvement I provide means for adjusting the wick from below the lamp-reservoir, whereby the use of screws or analogous devices, which are expensive in construction and relatively slow of operation, is avoided. My wick-holder is advantag-cous, because it provides means whereby the means 'l'or adjusting the wick can be readily seen and operated below the reservoir, and is especially adapted for use in so-called hanging lamps.7

IVhat I claim as my invention, and desire to secure by Letters Patent, is-

l. In a central-draft lamp, the combination, with a wick-tube, of a wick-holder secured to a wick, a sliding rod detachably secured to the wick-holder and extended upwardly above IOC the reservoir, a sliding rod secured to the upper end of the first-named rod by means of a thread and nut and extended downwardly through the reservoir below the same, and a 5 tube through the reservoir, through which said downwardly-extending portion extends, substantially as speeied.

2. In a central-draft 12unp,the combination,

with a wick-tube, of 'a Wick-holder secured to 1o the Wick, a sliding rod detaehebly secured to the wiekeholderzm d extending above the lampreservoir, a sliding rod secured to the upper end of the first-named rod and extended downward through the reservoir, and a ngerpiece below the reservoir surrounding said 15 downwardly-extending portion, substantially as specified.
